WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 610,383, datedSeptember 6, 1898. Application filed December 28,1897. Serial No.668,977. (No model.)

To all whom it may concern:

Be it known that I, EDWARD T. BURROWES, a citizen of the United States,residing at Portland, in the county of Cumberland and State of Maine,have invented certain new and useful Improvements in Window-Screens; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to an improvement in window-screens, and moreparticularly to that class known as sliding screens.

In fitting and adjusting screens to windowframes it is frequently foundthat the latter are not perfectly square and are more or less irregular,which necessitates planing or cutting down the edges of the screen-frameto secure the requisite fit. When the windowframe is notperfectlysquare,the rigid screenframe will not lie sufficiently close tothe jainb or sill at all points to exclude insects. In view of this factmanufacturers usually construct the screens somewhat larger than isnecessary, so as to allow for this after planing off for fitting. When afinished painted V -screen-is planed off, the'wood is left exposed tothe elements and soon deteriorates unless repainted.

The object of the invention is to provide a structure which will avoidthe necessity of cutting the frame or marring the paint when it isnecessary to adjust or fit it to a windowframe and to also avoid thenecessity of re= painting or finishing the same.

The invention is embodied in the construction and arrangement of partshereinafter described, and defined in the claims.

In the accompanying drawings, wherein like letters of referencedesignate corresponding parts in the several views, Figure 1 is anelevation of a window frame and screen, showing a part of the latterbroken away. Fig. 2

is a detail longitudinal section of a part of a 7 shoe, showing themolding in section. Fig.

edgewisemovable A designates the jambs, and B the sill, of thewindowframe.

O designates the screen. On the edge of the screen-frame opposite theusual abutment-springs (1, which normally rest against the track orguide E, are arranged the justifying-shoes D, which are formed ofelongated concave strips designed to rest against the bead or track E onthe jamb. These strips have their ends bent down or offset, and theirlower portions F are formed conveniently with bifurcations G, leading infrom the ends.

H designates the adjusting screws, the heads of which are exposed andlocated on the inwardly-bent end portions F of the shoes below the planeof the base of the concaved surface. The stems of the screws are passedinto the bifurcations and loosely fit, so that the screws can be easilyturned therein. Immediately below the shoes are the collars h, rigid onthe screws, so that any outward movement of the screws independent ofthe shoes is prevented.

The ends of the shoes are located in recesses K, formed in the moldingof the frame, while the screws are forced into the molding, as shown. Asthe adjusting-screws are arranged at each end of the shoe, it is evidentthat the shoe can be adjusted outward at an incline or parallel with thescreen-frame, as occasion demands.

In Figs. 4., 5, and 6 is shown a slightlymodified form of connectionbetween the shoe and the adjusting-screws. In this form the heads of thescrews are secured loosely to the ends of the shoes by flanges It,struck up from the metal of the shoe. The heads of the screws are placedbelow the shoe, and an opening it is made in the latter directly abovethe screw-head and of a diameter less than the same, and the flanges arebent inward over the inner face of the screw-head.

With both forms the plates and screws are held from independentout-and-in movement.

In operation, should the window-frame be irregular or out of true, somuch so that the bottom bar of the screen would not properly fit thesill, it is only necessary to move or adjust the' justifying-shoes tocompensate for the irregularity. The screws having exposed heads areforced in or out by the aid of an ordinary screw-driver. It willtherefore be seen that if the screen does not fit the window-frame itcan be quickly made to do so by the justifiers in connection with theside springs, thereby avoiding the necessity of cutting or marring itsedges.

I am aware that various changes in the construction shown can be madeand substituted therefor without in the least departing from the natureand principle of the invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is

1. In a window screen, the combination with the frame, ofjustifying-shoes at the edge of, the frame consisting of elongatedplates and screws having exposed driving heads loosely secured to theplates at opposite ends free to rotate, substantially as described.

2. In a window screen, the combination EDWARD T. BURROWVES.
